ELECTRIC-LAMP GUARD.

Application -led February 19, 1917.

To all whom t may concern:

Be it known that I, CYRIL VoNDRAsHEK, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new'and useful Improvements in Electric- Lamp Guards, of vwhich the following is a specification.

This invention relates to certain new. and useful improvements in electric lamp guards.

The primary object of the invention is the provision of a guard for an electric lamp especially serviceable as an attachment for the reflector of an incandescent lamp, the structure being such that the guard may be easily applied and removed therefrom and an inclosed lamp serving to prevent any injury to the lamp when in its operative position.

A further object of the device is the provision of a lamp guard that iseasy andinexpensive to manufacture, serving to protect against breakage while offering only slight obstruction for the rays of light emanating therefrom, the device be-" ing adapted for instant attachment to the usual substantially flat reflectors commonly employed with incandescent lamps of either the wall, electrolier or drop-light variety.

The invention consists of the novel'combination and arrangement of parts hereinafter described and claimed as well as illustrated in the accompanying drawing in which like reference characters designate corresponding parts throughout the several views and in whichz- Figure 1 is a diametrical sectional view through the device and a mounting reflector illustrated in connection with an incandescent electric lamp.

Fig. 2 is a top plan view of the reflector removed from the lamp with the device attached thereto.

Fig. 3 is an'enlarged detail View of anv edge section thereof partially broken away illustrating an end connection for one of `the mounting members, and,

reflectors as at 10 herein illustrated,l being Specification of Letters Patent.

fflector 10 with the rim Y vlower face of the reflector adjacent its pe- ?atented Sept. 25, 191'?. semi No. 149,5o.

`in connection with an electric lamp of the usual form comprising an incandescent bulb 11 and a socket 12 and to which socket the said reflector is removably secured by means of a collar form of mount 13.

The guard of my invention consists of a foraminous wire basket 14; preferably formed of a metal screen or netting 15 having a mesh of suitable dimensions, the struc ture being substantially semi-circular in cross-section and provided with a rim or binding strip 15 secured at its circular edge and forming an open side for the device.

A mounting wire or bail 16 forming substantially a cord of the rim 15 is secured to the latter by projecting the opposite ends 17 of the bail through the said rim from points exterior thereof and clenching said. ends inwardly of the rim in angular arrangement, as best illustrated in Fig. 3 0f the drawing. The bail 16 is adapted for slipping over a peripheral portion of the re- 15 seated upon the ripheral upturned bead 18.

The bail 16 has U-shaped terminal por-v tions 19 for accommodating the shade bead 18, the portion of the said bail positioned therebetween being arcuate substantially conforming to the curvature of that portion of the reflector `10 which is engaged thereby when the guard is operatively positioned upon the reflector. A retaining latch 20 is pivotally carried bythe rim 15 at 'a point' thereon diametrically opposite the center of the bail 16. The said latch 20 is preferably constructed of resilient wire be` ing of loop formation angularly bent as at 21 for engaging over the bead 18 of the reflector 10 when operatively positioned and at which times the closed end portion 22 of the latch flatly engages the upper face of the reflector. The latch 21 is formed of a single piece of wire having its ends bent in the form of eyes 23 which are pivoted through suitable perforations in the rim 15, the construction being substantially a swinging double hook adapted to'be release fromv the reflector' by pivotal movement outwardly as illustrated by dotted lines in Fig. 1 of the drawing. It will be understood that thev connecting portions of the wire forming the eyes 23. may Ytogether as at 24 while the bail ends 17 may be soldered to the rim 15 as at 2.5. The said rim being here shown U-shaped in cross section and secured to the basket 14 by be soldered ico crimping, may be of any desired form, it being noted however, that the loops 23 of the latch 2O as well as the end portions of the loop 16, all extend through the rim 15 and inclose an adjacent portion of the material -of the basket 14, thereby assisting in retaining the rim thereon. A different form of latch 26 4which is serviceable with the device is illustrated in Fig. 4 of the drawing, the same being constructed of a single plece of resilient w1re bent in the form .of a U- shaped portion 27 with its loops 28 and parallel laterally projecting V-shaped bends29 while eyes 30 are formed in the f ree ends of the wire in which the latter is constructed for hinged attachment to a lamp guard rim 15. The latch 26 is operable in a manner identical to the latch 20 heretofore described, the bends 29 forming engaging lugs for overlying the reflector bead 18 in a manner which will be at once apparent from an inspection of the drawing.

In applying the guard to the reflector 10, the same is positioned with the guard rim 15 flatly engaging the same therebeneath and with the bail 16 overlying the refiector as before stated while the lamp globe 11 'will project into the guard being inclosed by the guard and reflector, the latch 20 being sprung upwardly over the reflector bead 18 in resilient engagement therewith and with the upper surface of the reflector.v It

will be apparent that this form of guard may be readily attached to and detached from the reflector 10 while the glass globe 11 will be protected by the inclosing basket member 14. While the present form of the device is believedV to be preferable, minor changes may be made if desired without departing from the spirit and scope of the invention as claimed.

What I claim as new is 1. ,A lamp guard comprising a wire mesh basket substantially semi-circular in crosssection, a rim U-shaped in cross-section inclosingly overlying the edge of the basket, a bail positioned in cordal relations with respect to the rim having outwardly projecting substantially U-shaped end portions and an arcuate portion therebetween, the terminal portions of the bail extending through the sides ofthe rim and the adjacent'portions of the basket positioned therebetween,

and the inner faceJ of the rim, and a resilient retaining latch hinged to the rim at a point thereon diametrically opposite from the cen' ter of the bail.

l2. A lamp guard comprising a wire mesh basket substantially semi-circular in crosssection, a rim U-shaped in cross-section inclosingly overlying the edge of the basket, a bail positioned in cordal relations with vto the rim at a respect to the rim having outwardly projecting substantially U-shaped end portions and an arcuate portion therebetween, the terminal portions of the bail extending throughfthe sides of the rim-and the adj acent portions of the basket positioned therebetween, securing means between the ends of thebail and the inner face of the rim, and a retaining latch formed of a single piece of bent resilient wire of hook formation having terminal eye portions projectingv i through the rim and the adjacent portion of the basket and pivotally carried thereby, the eye portions serving to retain the edge of the wire mesh in position in the rim;

3. A lamp guard comprising a forami'' nous basket, a circular rim secured in binding engagement with the edge thereof, an arcuate bail secured between opposite points rim carried by the basket adapted for 'latv engagement beneath the reflector when operatlvely positioned, a bail carried by the rlm` adapted for overlying the reilector in contact with the upper face thereof, a resilient latch of hook form pivoted to saidriin at a point diametrically opposite the center of said bail adapted for overlying the. marginal bead of the reflector with the end of the latch in l'lat engagement with the upper face of 'the reflector when in its operative position.

6. In a lamp protector, an inclosingrnember, a retaining .latch thereon and formed of a single piece of wire bent into U-shaped'formation, the ends of the wire being bent upon themselves to provide looped portions, with the terminal ends bent to provide eyes adapted for pivotally mounting thedevice, the main shanks of the wire between the bight thereof and the portionsbent upon themselves, being further bent to provide U-shaped bends forming lugs adapted for overlying the bead portion of a reflector when operatively positioned thereon, and in substantially vertical alinement with respect to the pivotal eyes.

In testimony whereof I aliX my signature.
